Multilevel Deficiency of White Matter Connectivity Networks in Alzheimer’s Disease: A Diffusion MRI Study with DTI and HARDI Models

Figure 5

ROIs that have the reduced nodal efficiency in the AD group compared to the NC group (), given by the DTI and HARDI methods, respectively. Each sphere represents the center of an ROI and its size is proportional to the nodal efficiency. Refer to Table 2 for the label of each ROI.
